There is both, horiz and vert blanking circuits. The adjustment on the flyback sets the 'static' focus voltage, which is a DC voltage applied to the focus electrode in the CRT. Stuff like OSD and teletext features are right inside of the TDA9587H IC itself. PAL systems have a RP2A07G CPU and a RP2C07-0 PPU. When I add RGB to a consumer set, I look for a pin on the Jungle I/C that can totally control the H-Phase, It's typically driven by a low voltage current.

I have this CRT tv which I'd like to use for mister (yes, I am well aware of the dangers of CRTs' high voltage.

The voltage of both end of C911 is the DC voltage approx.

Retrace lines are caused by a defective blanking circuit or the brightness turned up too high.

External sync signals must be supplied from the graphics device. I made sure to use the correct level conversion for the signals, and I fed the RGB into the on board voltage divider coming out of the microcontroller pins. I added the resistors to my card so that I can turn off the individual guns. When current stronger than 350 в™љ flows, blanking takes place due to the internal blanking and OR logic circuit. Im not sure if any of this is correct thoughts ? Edited by The blanking consists in forcing a вЂњblackвЂќ level to the internal clamped video signal. 32 YS2 Switches between the internal RGB signal and analog RGB (pin 33, 34, 35) signal. That way you could switch between the RGB input and the normal, unmodified operation. Equation The total wattage of your LED strip lighting has to be at least 20 percent less than the power supplyвЂ™s rated wattage. DC 31 VP output Outputs the vertical pulse. A DIY RGB to Component Video Transcoder to make your own video conversion boxes. So when making a cable, ensure you have 9-12V at pin 8 of the SCART lead and that the blank signal is 1-3V. Suspect a bad electrolytic capacitor in one of those circuits. Industry-standard LCD technology replacement units are recommended.

Another thing I learned is your DC voltage must be very clean on 1500 volts you cannot have 10 volts of ripple, and also the tube is very sensitive to external magnetic fields.

After looking over the datasheet for the TDA it states 'input voltage to blank the RGB outputs to facilitate 'On Screen Display' signals being applied to the outputs' with a min of 4v. 3 MHz LPF VREF_IN FSADJUST DAC DAC DAC DAC CVBS/B 9 GAMMA Correct Color Space VREF_OUT Latch R G B HSYNC* VSYNC* BLANK* CLKX2 CLKX1 PAL INTERLACE SQUARE GAMMA* YCMODE RGBOUT IIC DATA IIC CLOCK Convert Mod. I therefore usually switch these pulldown resistors to 10K resistors, but here, that is then not needed. The outputs of the LM2419 are AC coupled to the cathodes (see Figure 13) so that cutoff voltages greater than 80V can be accommodated at the cathodes.

You can use it to play pc games on real hardware, and it's amazing for emulating too, especially if you can get 240p to work. It appears to infant have RGB outputs as well as the blanking pin that will be tied to presumably 5v to get the whole picture to fill the screen.Selection is controlled by the voltage at the RGB switch control (pin 21) and mixed RGB modes are
